mjb/altos/src, branch 1.5.9.1

Set version to 1.5.9.1

altos/lpc: Switch LPC SPI driver to interrupt-driven

2014-12-23T01:27:09+00:00

This improves performance for SPI transfers, while allowing other tasks to get work done during longer SPI transfers. Signed-off-by: Keith Packard

altos: Adjust CC1200 RSSI reporting value

2014-12-23T01:11:51+00:00

On the test setup, we were about 13dB off, so tweak the settings to suit. This result wasn't tested; it's just a rough offset until we get a production run of TeleDongle boards back to do more systematic measurements. Signed-off-by: Keith Packard

altos: Document cc115l power measured at RF setting 0x03 as -31.75dBm

2014-12-23T01:10:33+00:00

We built a custom TeleGPS load for radio sensitivity measurements with the lowest documented power level setting (0x03), and measured the power out at that value of -31.75dBm on the test board. Signed-off-by: Keith Packard

altos/cc1200: With PQT wide open, we can't use PQT_REACHED for start

2014-11-24T02:56:40+00:00

Because we're allowing even signals only weakly correlated with the preamble through to sync detection, we can't use the PQT_REACHED symbol to tell when a packet header has been seen. Instead, just look for SYNC_FOUND. Signed-off-by: Keith Packard

altos/cc1200: Open up preamble detect to improve sensitivity

2014-11-24T02:50:57+00:00

Increase soft decision PQT value to max (15) to ensure that we detect even weak packets. Signed-off-by: Keith Packard

altos/cc1200: Wait for packet to be placed in FIFO during receive

2014-11-24T02:31:15+00:00

This changes the receive code to use MCU_STATUS, waiting for MARC_STATUS1 to indicate that the packet is in the fifo before reading it out. It also fixes the receive timeout code to keep receiving if the preamble or sync have been seen when the timeout fires. This makes TeleLCO able to use short timeouts during scanning while still successfully receiving packets. Signed-off-by: Keith Packard

altos/teledongle-v1.8: Make this the same as teledongle v1.9

2014-11-17T00:40:27+00:00

Remove RSSI LED blinking, add CRC error LED Signed-off-by: Keith Packard

altos: Allow TeleMega to be built without MPU6000

2014-11-17T00:40:26+00:00

Robert Braibish's board has a dead MPU6000; this fix lets the TeleMega firmware build without that driver so the rest of the board could be verified. Signed-off-by: Keith Packard

altos/microsplash: fix .gitignore to ignore resulting binary

2014-11-16T21:41:27+00:00
